Title: Process and receptacle for the cultivation of mushrooms
IPC: A01G1/04
Filed: 1987-10-31
Abstract: In the case of known systems for the cultivation of edible mushrooms, controlled growth is not possible since the nutrient substrate is exposed to the constant action of air and light and the mushrooms grow without the possibility of being influenced from outside. In order to achieve controlled growth, provision is made for the nutrient substrate, along with the mushroom spawn, to be introduced into a bag consisting of a light-impermeable material, with the result that the mushrooms can only emerge through special, closeable growth openings. The process and the receptacle suitable therefor are suitable, in particular, for the cultivation of edible mushrooms by the consumer. <IMAGE>

Title: Commutator for an electric motor, and a reinforcing ring for it
Inventor: NETTELHOFF FRIEDRICH W
IPC: H01R39/14
Filed: 1988-04-15
Abstract: A commutator for an electric motor and a reinforcing ring for it are produced in such a manner that the reinforcing ring has an inner supporting ring and outwardly directed projections by means of which an anchorage to the commutator laminates is produced. Such a reinforcing ring is easy to install and creates a high load capacity. It can furthermore be completed to form reinforcement which also surrounds an inner bush. If designed from insulating material, such an inner bush produces double insulation and allows a precise push fit for pushing onto a motor shaft to be specified.
Patent DE-3812838-A1 (DE)
Title: Small unit for the shock wave treatment of disorders
Inventor: SCHUBERT WERNER DR MED
IPC: A61N7/00
Filed: 1988-04-18
Abstract: The physical, local and thus gentle therapy of various disorders requires small units for shock wave treatment which act without heating of the tissue and/or the pathological focus by emulsification or dispersion inside the body through the intact skin, extracorporeally by means of shock wave generators. In contrast to the lithotriptor which has hitherto been used solely for crushing of concrements, such a small unit does not require a stand. Coupling is effected directly on the body of the patient with a differentiated coupling device which possesses water as the coupling medium in a cushion-like enclosed space. Fitted shock wave generators or vibrating bodies are to be introduced in chambers of the coupling device that are accessible from the outside. Field treatments above the heart such as for the treatment of the important sclerosis of the coronary artery are possible, as well as focussed or strip-like introduction of shock waves for the treatment of tumours and of arteriosclerosis in other parts of the body. The coupling device can be supplemented by various adjustment devices such as adjustment strips, for example for the mid-line of the body above the heart, holding bolts on this adjustment strip for the coupling device or tapes on the coupling device for fastening on the body of the patient.

Patent DE-3827978-A1 (DE)
Title: Method and device for continuous lambda control
Inventor: SCHNAIBEL EBERHARD DIPL ING
IPC: F02D45/00
Filed: 1988-08-18
Abstract: In a method for continuous lambda control, the actual voltage of the probe is not used to form a probe voltage system deviation as in conventional methods but rather to form a lambda value system deviation. For this purpose, either the actual voltage of the probe is converted into an actual lambda value in accordance with a characteristic curve and the said actual lambda value compared with a desired lambda value or the actual probe voltage compared with a desired probe voltage and the calculated probe voltage system deviation is converted into a lambda value system deviation with the aid of a characteristic curve. This method permits continuous control even when using a probe with a highly non-linear characteristic curve. Advantageously, corrections for compensating temperature effects of the characteristic curve and for compensating offset voltages are still carried out. A device for carrying out the aforesaid method has in particular a device for performing the aforesaid conversions of voltage values into lambda values. <IMAGE>

Title: Device for measuring the degree of hydrophilicity of fibrous material
Inventor: STAPPER-DRUYEN SYLVIA
IPC: G01N15/04
Filed: 1988-11-11
Abstract: In a device for measuring the degree of hydrophilicity of fibrous material, having a liquid bath and at least one sinking basket for the accommodation of the fibrous material, the personnel cost of the measuring method for sinking times over 10 seconds is intended to be considerably reduced without impairing the accuracy of the measured values obtained. This objective is achieved by means of an apparatus for maintaining a specific temperature of the liquid bath, by means of at least one light barrier arranged on the at least partially transparent walls of the water bath and arranged in such a way that its light beam is interrupted only upon the complete sinking of the sinking basket under the liquid surface, the spatial position of the sinking basket being irrelevant during the sinking, and by means of an evaluation apparatus connected to the light barrier and having a time measuring device which outputs the time between a starting signal and the interruption of the light beam. <IMAGE>

Title: Discharge cleaner based on water pressure
Inventor: KAESBERGER FRANZ
IPC: E03C1/306
Filed: 1988-11-18
Abstract: Since, up until now, it has only been possible to remove a discharge blockage either with chemical, environmentally harmful means or by high-outlay dismantling of the discharge system, the invention provides a discharge cleaner based on water pressure. With the aid of the water pressure of a water tap (6) or of a water-pressure pump (7) (pressure of at least 3 bar), water is channeled into a hemispherical cap (1) via a water hose (5) which is connected to a pressure-resistant pipe (2) by means of a connection nipple (4). By means of the water pressure arising in the hemispherical cap (1), which fixedly encloses and seals the discharge opening (10), the discharge blockage is forced downwards and removed. The water or any other liquid can then be freely discharged. The water jet can be stopped and the water pressure can be regulated via a shut-off device (3) on the pressure-resistant pipe (2); as a result, simple and clean handling is likewise possible. <IMAGE>
